Computer organization

I have an Apple imac with several external drives that need organized and a folder and file labeling workflow that should be implemented for better workflow. I am a photographer and video editor and I just did not have a good workflow with saving out my files from the beginning as well as I have hard drives copied over to my new hard drives. I would like some one with exceptional organization skill to help me organize my drive and create a new way to save files that works better for me. First freelancer will write out method that will be used and get me a copy prior to hire. so I can see what we will be doing.
